Create an Amazon Machine Image (AMI) containing your
applications, libraries, data and associated configuration
settings. Or use our pre-configured, templated images to
get up and running immediately.
Upload the AMI into Amazon S3. Amazon EC2 provides
tools that make storing the AMI simple. Amazon S3
provides a safe, reliable and fast repository to store your
images.
Use Amazon EC2 web service to configure security and
network access.
Choose the type(s) of instance you want to run.
Start, terminate, and monitor as many instances of your
AMI as needed, using the web service APIs.
Pay for the instance-hours and bandwidth that you
actually consume.

the vision -- reduce the cost of computing,
increase reliability, and increase flexibility by
transforming computers from something that
we buy and operate ourselves to something
that is operated by a third party.

大学，加利福尼亚大学伯克利分校，马里兰大学和
华盛顿大学。
 学生们学习如何调整自己的程序来适应Google计算机，并雄心勃勃地设计开发网络
规模的项目
 这些数据可能用于开发新药品和疗法、制造新的清洁能源、甚至预测地震
